Integration with ORNO OR-WE-504


The purpose of this article is to present an example of integrating the energy meter with the Grenton Smart Home System. The following integration is using the Modbus RTU communication protocol.

The energy meter used in this example is ORNO OR-WE-504 . Documentation of this device is available here.

This integration allows us to receive the following information:

  • Voltage
  • Current
  • Frequency
  • Active power
  • Active energy

To complete this example, we need:

  • CLU Z-Wave
  • Gate Modbus
  • ORNO OR-WE-504 


Configuration of Modbus periphery objects

1. Create Modbus virtual object:

2. Add Modbus periphery objects:

  • Voltage:

  • Current:

  • Frequency:

  • Active power:

  • Active energy:
